My sincere thanks to WiKID, who have sponsored my writing for the last week. Check out their two-factor authentication solution - which is free for five users. Thanks guys!

Here is how they describe their product:

The WiKID Strong Authentication System is a dual-source, on-premises two-factor authentication solution for enterprises. The WiKID server is simple to implement and maintain, highly reliable and supports all Enterprise-class remote access and privileged account solutions.

The WiKID server is available as a virtual appliance - no Linux experience necessary or as DEB/RPM packages.

Security researchers have warned about a widespread vulnerability in Android devices, that could see attackers sneakily modify or entirely replace seemingly benign apps with malware, without users becoming aware.
